Things I'd like to do/fix:
  - Search for "existing" in returned table text and replace with generated things
    - NOTE: Faction may be easiest
  - Replace 1d6 rolls with helper
  - Get rid of helpers.go
  - Cross-platform shell in Makefile
  - Figure out how to distribute web/ in binaryfile
  - Add PORT env var/flag (super easy)
  - Generate truly unique list of items (handle impossible requests, expensive computation)
  - Pointer on MazeTable?
  - Support rooms variable on City/Maze
